Detailed Description

Subclass of value for objects: a collection of key/value pairs preserving the ordering in which keys were inserted. Preserving the order eliminates non-determinism in the output, making it easier for the user to compare repeated invocations.

Member Function Documentation

◆ compare() [1/2]

int object::compare ( const json::object & obj_a,
const json::object & obj_b )
static
Subroutine of json::compare for comparing a pairs of objects.

References json::value::compare(), gcc_assert, get(), m_keys, and m_map.

Referenced by json::value::compare().

◆ compare() [2/2]

int value::compare ( const json::value & val_a,
const json::value & val_b )
staticinherited
A deterministic total ordering for comparing json values, so that we can e.g. put them in std::map. This is intended to follow the condition for equality described in the JSON Schema standard (§4.3, “Instance equality”), as referenced by SARIF v2.1.0 (§3.7.3 "Array properties with unique values"), but has the following limitations: - numbers are supposed to be checked for "the same mathematical value", but in this implementation int vs float numbers won't compare as equal, and float number comparison is bitwise - strings are supposed to be "the same codepoint-for-codepoint", but this implementation doesn't take into account canonicalization issues.

◆ dump() [1/2]

void value::dump ( ) const
inherited
A convenience function for debugging. Dump to stderr with formatting, and a trailing newline.

◆ dump() [2/2]

void value::dump ( FILE * outf,
bool formatted ) const
inherited
class json::value.
Dump this json::value tree to OUTF. The key/value pairs of json::objects are printed in the order in which the keys were originally inserted.
